SPECIFICATION forming part of Letters Patent No. 500,024, dated June 20, 1898.

Application filed March 10, 1893. Serial No. 466,383. (Nospeoimene) To allwhom it may concern:

Be it known that I, ALPHONSO MONROE, a

citizen of the United States, residing at Poyntell, in the county of Wayne and State of 5 Pennsylvania, have invented new and useful Improvements in Roofing Compounds, of which the following is a specification.

. My composition consists of the following ingredients, combined in the proportion [0 stated, viz: Portland cement two hundred and fifty poundssand tour Hundred pounds; 'laster of aris one Hundred poundscrude etroleum, one gallon; tur entine one-lialt gallon; fine salt one-halt pecE' wai rin' suf- 15 fifient quantity to reducethe whole to a thin p aster. I

To prepare the compound the cement, sand and plaster of paris, are first mixed together, while in a dry state. The crude oil, turpen- 2o tine, and salt are next added to about a halfbarrel of water, and thoroughly mixed therewith, and the liquid produced is then poured over the dry compound, and mixed therewith by means of a hoe, or with any suitable apparatus, so as to produce a plaster which can 25 be applied to the roof by means of an ordinary trowel. Additional water can be added, it required, at the time of making the compound, or at any time thereafter.

-I find by experimentthat the turpentine 30 causes the compound nlolh 'unuch sgoneg t an it otherwise would; a at by the use of salt,

as stated, alldanger of freezin isaverted,

especially w on ecompoundis'first applied.

What I claim, and desire'to secure by Let- 5-.
